I have been trying to install DNN 7 but it got stucked at the first step of installation. Giving the error "No valid default database connection detected. Standard Database setup option is unavailable Database Connection Error"
ERROR:Index #: 0 Source: .Net SqlClient Data Provider Class: 20 Number: 53 Message:
Anyone knows what to do?
This occurs if you try to install DNN using SQL Express, but you don't have SQL express installed, or you don't have it installed with the default instance name.
You can do one of the following things.
1) Install SQL Express 2) Connect to a different database server.
